The extent of the damage isn't yet clear and the six deaths reported so far may be followed by news of other fatalities.

"The Pacific Tsunami Warning Center said the quake generated a large tsunami with the biggest wave reported at about 2 meters. The Chilean navy said the first big wave hit the coast within 45 minutes. Early on Wednesday Chilean authorities canceled their tsunami warning for most coastal areas."

NPR's Lourdes Garcia-Navarro, who has been monitoring the news from Brazil, tells our Newscast Desk that "for most of the night, residents of northern Chile huddled in shelters after most of the coast was evacuated. ... But it could have been much worse, according to observers and newly inaugurated President Michelle Bachelet. She took to the airways to praise the country's preparedness. ... A mostly orderly evacuation followed after the quake struck."

According to the U.S. Geological Survey, the temblor's epicenter was in the Pacific Ocean about 59 miles west of Iquique, Chile, and about 12.5 miles below the seabed. It struck around 6:46 p.m. local time — 5:46 p.m. ET.

The Associated Press says "the quake was so strong that the shaking experienced in Bolivia's capital about 290 miles away was the equivalent of a 4.5-magnitude tremor, authorities there said."

The wire service adds that:

"The extent of damage from Tuesday night's quake couldn't be fully assessed before daybreak, [Chilean] President Michelle Bachelet said, but she wasn't taking any chances. She declared a state of emergency in the region and sent a military plane with 100 anti-riot police to join 300 soldiers deployed to prevent looting and round up escaped prisoners.

"The shaking loosed landslides that blocked roads, knocked out power for thousands, damaged an airport and provoked fires that destroyed several businesses. About 300 inmates escaped from a women's prison in the city of Iquique. In Arica, another city close to the quake's offshore epicenter, hospitals treated minor injuries, and some homes made of adobe were destroyed, authorities said."

As Wednesday dawned, news outlets were reporting that at least six people had been killed. "Tens of thousands" had been evacuated, the BBC writes. It adds that "officials said the dead included people who were crushed by collapsing walls or died of heart attacks."
